BARREL-HEATER.

SPECIFICATION forming' part of Letters Patent N o. 689,294, datedDecember 17, 1901.

Application led October 23, l900.' Serial No. 34,030. (N0 model.)

T0 @ZZ whom, t may concern.-

Beit known that I, ELMER E. DoUGLAss, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Barrel-Heaters, of which the following is a full, clear,and exact description, reference being had to the accompanying drawing,forming part of this specication, in which the figure is a sideelevation, partly in section, of my improved barrel or keg heater.

My invention relates to apparatus for heating or charring the interiorof barrels or kegs. In apparatus heretofore employed-for this purpose ithas been found difcult to evenly heat or char all parts of the innersurface owing to unequal distribution of the heat. My invention isdesigned to overcome this difficulty; and it consists in employing anannular series of gas-burners, the ame and gases from which passupwardly within a shield or case and then enter a centraloutletilue,which extends downwardly throughthe space within the annularseries of burners.

It further consists in providing a heatingdrum with a mass of heatedlump material which extends the major portion of the length of the drum,the drum having an upper outlet for the gases. The refractory materialthus extending up within the drum diluses and extendsthe combustion,thus giving a more extended and uniform heating of the mass and a moreuniform charring of the keg or barrel.

It further consists in the construction and arrangement of the parts, ashereinafter more fully described, and set forth in the claims.

In the drawing, 2 represents a stand or platform carried on supports 3,and 4 is an annular barrel o'r keg support mounted thereon.

5 is a cylindrical heating-drum having a top cover or closure 6, thisdrum being of a suitable size so that the keg or barrel 7 may be slippeddown over it. At the lower end of the drum an annular blast-box 8 isformed, through the top of which project a series of burners 9. Belowthe box 8 is an annular gas-chamber 10, from which a series of tubes 11project upwardly into the burners, the gas and air mixing within theburners in the usual manner. Air is supplied to the windbox through apipe 12, and gas is similarly supplied to the gas-chamber through a pipe13, these pipes having suitable controllingvalves.

To the center of the platform or table is secured a depending box 14,Within which is carried the oiftake-iiue 15, which is preferably formedof hollow tiles and extends up- Wardly to within a short distance fromthe top of the drum. From the lower end of this offtake-flue l5 leadsthe stack-fine 16. The annular space between the central offtakeue andthe heating-drum is filled with-refractory material 17, which ispreferably in the form of broken pieces of tile or fire-brick.

4In using the apparatus, the keg or barrel being set down over the drum,the flame and gases from the annular row of burners, passing up throughthe annular belt of refractory material, heats it to a high temperature,and this heat is radiated through the drum to the inner surface of thekeg or barrel. The products of combustion entering the top of the flue15 pass downwardly through it into the stack.

The advantages of my invention result from the even and uniform heatwhich is obtained by using the annular series of burners within the drumand also from the use of the refractory material, which stores up theheat and equalizes the heat throughout the drum, so as to give an evenoharring of the barrel. The placing of the apparatus upon the elevatedtable is also of advantage, since it permits a free circulationof airbeneath the stove and also serves as a support for the stack-iiue.

Many changes may be made in the form,

size, and arrangement of the parts without departing from my invention.

I claim-a 1. A barrel a heater having a cylindrical drum, a basearranged to support the barrel or keg in position around the drum, acentral offtake-iue extending downwardly from within the upper part ofthe drum, an annular zone of granular refractory material be tween theflue and the sides of the drum and arranged to extend upwardly the majorpart of the length of the keg or barrel, and gasi burners projectingupwardly in the space containing the refractory material; substantiallyas described.

2. A barrelheater having a cylindrical heating drum, with a centralofftake iiue therein, a base arranged to support a barrel 'or keg inplace around the drum, and an annular belt of heated lump materialbetween the iue and the drum, and arranged to extend upwardly the majorpart of the length of the barrel or keg; substantially as described.

3. A barrel-heater having a heating-drum carried on an elevated base orsupport arranged to allow air circulation below the heater and supportthe barrel or keg around the drum, a mass of heated lump material withinthe drum and extending the major part of the length of the barrel orkeg, an upper outlet for the gases, and burners projecting upwardly intothe space lled with the lump material; substantially as described.

4. A barrel-heater having a heating-drum provided with acentraldowntake-flue and a zone of refractory material between the flue anddrum and extending upwardly the major portion of the length of the drum,an annular box below the drum, an annular series of mixers provided withburners projecting upwardly into the annular space containing thegranular material, and a base arranged to support the barrel or kegaround the drum substantially as described.

5. A barrel-heater having a heating-drum with a central offtake-due, abase arranged to support the barrel or keg around the drum, a zone ofheated lump material between the fiue and drum and extending upwardlyfor the major part of the length of the drum, an

annularair-blast box beneath the drum, mixers having burners leadingfrom the blast-box into the refractory material, and gas-supply tubesleading into the mixer; substantially as described.

6. A barrel-heater having a drum containinga mass of heated lumpmaterial extending the major portion of the length of the drum, saiddrum having an upper outlet for the gases, and a base or supportarranged to carry the barrel or keg in place around the heating-drum;substantially as described.

7. A barrel-heater having a drum containing a mass of granularrefractory material extending upwardly for the major portion of thelength of the drum, said drum having an upper outlet for the gases, abase arranged to support a barrel or keg in position around the drum,and burners arranged to direct their iiames upwardly into the refractorymaterial; substantially as described.

8. A barrel-heater having a heating-drum with a central oiftake-flue andsurrounding refractory material extending upwardly for a major portionof the length of the drum, an annular Yblast-box beneath the drum withburners projecting upwardly thereinto, a rest around the lower part ofthe drum to receive the barrel, and an annular gas-chamber loeneath thewind-box with gas-supply tubes leading upwardly into the mixer;substantially as described.

In testimony whereof I have hereunto set my hand.
